NO COMPROMISE.
NO LIMITS.

Developed in close collaboration with CUBE athlete and World champion Lucy Charles-Barclay, the Aerium C:68X can rightly claim its title as the fastest frame we've ever made. Every detail, from the aero fork design, disc brake integration and in-frame hydration and storage systems has been designed with zero compromise, tested in the wind tunnel and then tested again under pressure, in race conditions. Lucy has full confidence in the frame and its configurable storage and hydration and now you can, too.

At CUBE much of our inspiration comes from working with athletes like World champion Lucy Charles-Barclay. While she hones her performance, we're busy building a bike that'll enable her to realise her potential even better. The Aerium C:68X combines sophisticated wind tunnel analysis with real world experience of racing. The result? Our most aerodynamic frame yet, with disc brake compatibility and a host of adaptable cockpit, storage and hydration options that are fully integrated so that everything is at your fingertips. Lucy particularly wanted to be as self-sufficient as possible, even on longer races, so we added the option of running up to two hydration systems in combination with our already well-established modular storage units – and an aero cover for the front derailleur mount means you can run 1x or 2x gears with no aero downside. Crafted from our premium C:68X® carbon, it's the hidden advantage you've been looking for.
